thanks for the advice guys. ok, so gonna keep the global just-in-case and try to use my wa-handle knives for everything else
with the western handle stuff, think i'm also gonna keep the 240 gyuto, 240 suji and 150 petty. been checking out dave martell's re-handling work and fancy doing that sometime! wanna re-profile the gyuto first though; at the moment i find the belly a little wide. not quite sure whether to take it down on the blade side or the spine side, or do a combo of both sides. but guess i'll have a play and try to figure it out.
